Two things spring to mind at first, possibly a way to get started. First,
establish that it is not the game server relinquishing the port. This is
unlikely but it ought to get eliminated from consideration. sockstat -4l
will tell you what is listening to which ports. Next time it gets "closed"
take a quick look at this and ensure the game server is actually still
listening to this port. If it is not it is most likely a configuration
detail relevant to the game server.
Second, this sounds a lot like a NAT session timing out from inactivity. If
such a situation should be the case it is possible to design a rule specific
so the ports' traffic can bypass NAT and run "straight-through". If the
first thingy from above gets eliminated this is where I'd look next. As to
exactly how you would go about tailoring such a rule would depend upon the
syntax of whichever firewall you are using.
